BOOM FOOT PART OF WORK MACHINE
PROBLEM TO BE SOLVED: To secure rigidity of a boom foot part without impairing wiring workability.SOLUTION: A front side connecting plate 17 includes a front side extension part 17a that has a front edge side extending upward from a bottom plate 11 while being connected to a pair of right and left vertical plates 12, 13, is bent toward a rear edge side so as to face a rear side of a hydraulic shovel 1, and has right and left edges on the rear edge side extending toward a rear side connecting plate 16. A reinforcing plate 19 has a rear side extension part 19a of which right and left edges on a front edge side extend toward the front side connecting plate 17. The front side extension part 17a and the rear side extension part 19a are deviated in a vertical direction when seen from sideways, and form one continuous upper opening 20 by overlapping in an area sandwiched between the pair of right and left vertical plates 12, 13, when seen in a planar view.SELECTED DRAWING: Figure 1
【課題】配索作業の作業性を低下させることなく、ブームフット部の剛性を確保する。【解決手段】前側連結板１７は、前端側が底板１１から左右一対の縦板１２，１３と連結された状態で上方へ延び、後端側に向かって油圧ショベル１の後方へ向くように折れ曲がり、後端側の左右両端が後側連結板１６に向かって延びる前側延長部１７ａを有し、補強板１９の前端側の左右両端が前側連結板１７に向かって延びる後側延長部１９ａを有し、前側延長部１７ａと後側延長部１９ａとが側面視で上下方向にずれると共に、平面視で左右一対の縦板１２，１３で挟まれた領域に、重なり合って連続した１つの上方開口部２０を形成する。【選択図】図１
